To all whom it may concern:

Be it known that I, THEODORE Koorr, of No. 515 Western avenue,Milwaukee, Wisconsin, citizen of the United States, residing atMilwaukee, in the county of Milwaukee and State of Wisconsin, haveinvented cer- Pipeslools, of which the following is a specification.

This invention relates to improvements in tools" for removingobstructlons in sewer pipes, cisterns and other places where it isdesirable or necessar to remove obstructions and which are inaccessibleexcept for tools of comparatively small cross diameter and considerablelength.

The especial object of the improvements I which form the subject matterof this application is to provide a tool that may be inserted in a drainpipe, cistern or the like,

-which may be used in grasping and 'With-.

drawing obstructions placed in such pipes and which may be'provided withlighting devices so that the obstructions may be seen by the operatorwhile using the tool.

\Having these and other objects of general utility in view I haveinvented the device hereinafter described in detail and shown in theaccompanying drawings, ,in which Figure 1 is a side elevation of thetool, and Fig. 2 is a rear elevation of the same tool in its invertedposition.

Referring to the details of the drawing, 3 represents a wood star! orbar which may be of l any suitable len th and thickness. Se-

cured to one end'o this stafl by screws 5,

is a clasp composed of the back piece 4, and the clamping member 6mounted on the back piece by pivot 7, and held under tension by the flatspring 8 one end of which is secured to one end of the staff. To theupper end 11 of the clamping member is secured a chain 9 which travelsover a pulley 12 mounted in a suitable recess provided therefor in thestafi.

.The' upper endof the chain is secured to a staple 10 which is fixed inone side of the staff. Secured to the side of thestafl by screws 16 is afiat metal plate 15 to one end of which is secured a socket 13" adaptedto receive a candle'14. A similar plate 15 and socket 13 are secured atthe opposite end of the stafi. and at this end, a hook 17 is secured bybolts 1.8.

To use a tool constructed substantiallv as described the end of thestafi on whic the clamp is mounted, is lowered into the pipe or cisternor other place from which it is desired to remove obstructions and ifnecessary, the candle I4 is lighted so that the operator can see theobstruction and then by pulling upwardly on the chain 9 open the clampmgend of the member 6, and thus grasp the obstruction, which is withdrawnraising the staff. If the obstructionis. I

Having thus described my invention What I claim, 1s:- I
